This study analyzed the correlation between stress measurements calculated through HRV signals and thyroid function test items. 181 healthy adults without disease who visited Clinic K were the subjects of this study. Stress resistance (SR) and stress index (SI) were calculated using the acquired HRV signal, and TSH, Free T4, and T3 were used as thyroid function test items. For the measured values, the relationship between each item was statistically analyzed through Pearson correlation analysis. From the results, it was confirmed that Free T4 and SR had a positive correlation (r=0.18) and a negative correlation with SI (r=-0.16). Through this, it was confirmed that there is a significant relationship between thyroid function and HRV signal.

Objectives: Graves' disease is the most common cause of hyperthyroidism, and its pathogenesis includes thyroid specific autoimmunity. Anti-thyroid drugs are widely used for regulating the thyroid function. However, in spite of long-term therapy with anti-thyroid drugs, about 40$\sim$$70\%$ of the treated patients have a relapse, and some suffer adverse effects. In this study, to evaluate the clinical efficacy of Ahnjeonbaekho-tang(AJBHT) on Graves' disease patients, we performed the clinical study prospectively. Methods: Through the thyroid function test(TFT) of 54 patients diagnosed as Graves' disease in other hospitals, 21 patients were assigned into the study. After the withdrawal of anti-thyroid drugs, AJBHT was administerd to patients for 2 months. At the same time, TFT, TSH binding inhibiting immunoglobulin(TEII) level and visual analogue scales (VAS) about fatigue and palpitation were measured before and after administration. Thirteen patients have completed the entire follow-up of this study over two months. Results: Serum levels of T3 and FT4 were significantly improved by AJBHT(T3: 298.85$\pm$79.60 ng/dl 181.15$\pm$33.92 ng/dl p<0.0001, FT4: 2.78$\pm$1.06 ng/dl$\rightarrow$1.78$\pm$0.83 ng/dl p<0.05). However, there were no significant changes in TSH and TBII values. And the VAS scores of fatigue and palpitation also were significantly improved(5.80$\pm$3.01$\rightarrow$3.60$\pm$2.63, p<0.05; 6.19$\pm$2.09$\rightarrow$3.60$\pm$2.46, p<0.01). Patients' age was related to the post-treatment FT4 values(p<0.05). Conclusions: From these results, we suggest that AJBHT is effective on the TFT and the symptoms of Graves' disease, and is a safe alternative drug for Graves' disease patients.

Objective: This is aprospective clinical case study that includes the administration of Ahnjeonbaekho-tang (AJBHT) to patients who have suffered from Graves' disease for the 8 weeks of the clinical research. Methods: Without administration of an antithyroid drug, AJBHT was administered 3 times a day for 8 weeks. In Case 1, AJBHT without modification was administered and in Case 2, in accordance with the patients' symptoms, a dose of Gypsum Fibrosum was increased by 4g from the beginning of week 2, and further increased by 16 g, for a total of 20 g between week 6 and week 8. Body mass index (BMI), thyroid function test (TFT), thyroid autoantibody test, complete blood cell count (CBC), and blood chemistry (BC) tests were conducted at an interval of 4 weeks, for a total of 3 times during the study. The clinical manifestations, a spectrum of symptoms of the patients, was observed by Wayne's Index, Euro-QOL-5 Dimension (EQ-5D), and Perceived Stress Scale (PSS). Results: In both cases, an acceptable significance of reduction of value in T3, fT4, Thyroid stimulating antibody (TSAb) and Thyroid stimulating hormone receptor antibody (TSH-R-Ab) was observed. After treatment, in TFT, T3 decreased by 31.66%, fT4 decreased by 32.82% in Case 1, and T3 decreased by 43.42%, and fT4 decreased by 37.32% in Case 2. In the thyroid autoantibody test, TSAb decreased by 7.59%, and TSH-R-Ab decreased by 53.19% in Case 1, and TSAb decreased by 33.45%, TSH-R-Ab decreased by at least 7.75% in Case 2. Besides this, there was a decreasing trend of Wayne's index, and a loss of typical symptoms of hyperthyroidism also declared the efficacy. Conclusion: From these results, AJBHT is very effective in the regulation of TFT and improving the symptoms of hyperthyroidism, and is also expected to be an effective alternative to antithyroid drugs for patients who have side effects or drug intolerance.

Objective: Graves' disease, the most common cause of primary hyperthyroidism, is a thyroid specific autoimmune disorder. When resistance to medication is shown in spite of long term therapy with anti-thyroid drugs, radioactive iodine therapy would be chosen in Western medicine. However, this therapy has often been reported to cause patients have hypothyroidism, thus requiring them to take levothyroxine for the rest of their lives. In this study, we evaluate the clinical efficacy and safety of Ahnjeonbaekho-tang (AJBHT) on patients with Graves' disease. Methods: We prescribed AJBHT for 3 months to two groups: patients who had been taking antithyroid drugs were administered AJBHT after discontinuing the antithyroid drugs ($Com-Tx{\rightarrow}Single-Tx$), and patients who had not been taking antithyroid drugs were started with AJBHT (Single-Tx) immediately. We evaluated the thyroidal function test (TFT) and visual analogue scale (VAS) for clinical symptoms for 3 months. Results: Serum T3 and fT4 were significantly decreased in both groups and remission rate of thyroidal hormones were significantly improved in the Single-Tx group. The clinical symptoms of palpitation, fatigue, and heat intolerance were significantly improved in both groups. In the safety analysis, all patients were in normal range of liver, renal function blood test and common blood count. Conclusion: From these results, we suggested that AJBHT was effective on TFT and clinical symptoms of Graves' disease. The study supports that AJBHT may be a useful agent for patients with Graves' disease who are resistant to antithyroid medication or radioactive iodine therapy, and for patients at first diagnosis.

Squamous cell carcinoma(SCC) associated antigen is a subfraction of TA-4, a tumor-associated antigen first described by Kato and Torigoe in 1977. TA-4, obtained from squamous cell carcinoma cancer tissue of the uterine cervix, has been characterized as a glycoprotein with a molecular weight of approximately 45,000 daltons. SCC antigen has been studied in other squamous cell malignancies including lung, esophagus, head and neck, anal canal, and skin. SCC antigen is shed naturally through sweat, saliva and other body fluids. Contamination of specimens, tray, bead dispenser or other accessories with sweat, saliva or aerosols can cause falsely elevated values. To reduce the possibility of contamination, gloves should be worn in all phases of assay preparation, and when handling specimens, accessories or reagents that will be used in SCC and Thyroid function test(TFT).

Purpose : Thyroid hormone is essential for development of the brain in early life. Thyroid dysfunction is more common in the first 2-4 postnatal weeks of life in premature infants than in term infants. This study aimed to identify the prevalence and clinical course of thyroid dysfunction in prematurity. Methods : Premature infants admitted to and given neonatal screenings at Dankook University Hospital between April 1999 and March 2008 were included in this study. We retrospectively reviewed medical records and categorized subjects into six groups: normal, hypothyroidism, hyperthyrotropinemia, hypothyroxinemia, delayed onset of hypothyroidism, and delayed onset of hyperthyrotropinemia. Results : Among 599 subjects, 136 (23%) had initially abnormal thyroid function test (TFT); transient hypothyroxinemia was the most frequent condition (118, 20%). In addition, 8 (17%) of 46 subjects with initially normal TFT levels showed delayed onset of hyperthyrotropinemia with or without low free thyroxine ($fT_4$). Thyroxine was prescribed for 10 patients (1.7%) due to low $fT_4$ levels but was discontinued in 9 patients during follow-up. Thyroid scan confirmed ectopic thyroid in one patient. Conclusion : Thyroid dysfunction was frequently seen in premature infants, but most of the conditions were transient. In addition, some infants showed delayed TSH elevation on routine follow-up. Therefore, a recheck of the thyroid function of premature infants at 3-4 weeks is recommended, even if normal thyroid function is initially seen, especially in prematurity of less than 33 weeks of gestational age or birth weight of less than 2,500 grams.

Background and Objectives: Medullary thyroid carcinoma(MTC) is a rare tumor derived from the parafollicular C cells of the thyroid gland accounting for 5-10% of all thyroid malignancies. In Korea, there has been a few case report of medullary thyroid carcinoma(MTC) but their clinical analysis were not exactly studied. So, we made clinical study of 10 patients diagnosed as medullary thyroid carcinoma. Materials and Methods: We reviewed clinical data of 10 patients who were diagnosed as medullary thyroid carcinoma(MTC) from April 1973 to August 1998 at National Medical Center. Results: The incidence of MTC was 2.3% of all thyroid cancer and their mean age were 44.2 years old. Preoperative thyroid scan showed cold nodule in all patients and thyroid function test(TFT) was within normal range. Of the 10 patents, only 4 patients had diagnosis of MTC in preoperative fine needle aspiration biopsy. All the patients underwent total thyroidectomy with central neck dissection. Two patients with cervical lymph node metastasis underwent total thyroidectomy, central neck dissection and modified neck dissection. Two patients (20%) showed recurrence at the site of neck, lung, mediastinum, bone and liver. Conclusion: Most MTC is sporadic form and have peak incidence in the fifth decade and female preponderance. Preoperative fine needle aspiration biopsy is considered to be a clinically useful diagnostic method, but its accuracy is not considered as much high as others. Total thyroidectomy with central neck dissection may be an useful surgical modality in treating medullary thyroid carcinoma.

Objective: To assess the association with autoimmune endocrine diseases and detection rate of autoimmune antibodies and its clinical significance in patients with premature ovarian failure. Methods: Twenty eight patients with primary or secondary amenorrhea manifesting hormonal and clinical features of premature ovarian failure (primary POF: 7, secondary POF: 21) were investigated. We tested them TFT, 75 g OGTT, ACTH and S-cortisol for thyroiditis, IDDM, Addison's disease, and antithyoglobulin antibody, antimicrosomal antibody, antinuclear antibody, rheumatic factor, anti-smooth muscle antibody, anti-acetylcholine receptor antibody for non-organ specific autoimmune disorders. Results: Only one patient was diagnosed as IDDM and no patients had abnormal TFT or adrenal function test. More than one kind of autoantibody was detected in 11 patients of all (39.2%): 5 patients (71.4%) of primary POF group and 6 patients (21.4%) of secondary POF group. Eleven patients (39.3%) had antithyroglobulin antibody, 4 (14.3%) had antimicrosomal antibody, 2 (7.1%) had antinuclear antibody, 2 (7.1%) had rheumatic factor, 1 (3.6%) had anti-smooth muscle antibody, 1 (3.6%) had anti-acetylcholine receptor antibody. Conclusions: Premature ovarian failure may occur as a component of an autoimmune polyglandular syndrome, so patients should be measured with free thyroxine, thyroid-stimulating hormone, fasting glucose and electrolytes. Measurement of thyroid autoantibodies in POF patients may be important in identifying patients at risk of developing overt hypothyoidism, but other autoantibodies may not be suitable for screening test.

Objective : Thyroid diseases are one of the most common endocrine disorders. However, the first chosen-treatments including anti-thyroidal and hormone-supplement therapy in western medicines, sometimes have failed to improve abnormal thyroid hormone secretions and clinical symptoms. Therefore, there has been a growing expectation for Oriental Medicine to take the role of alternative therapy. However, there has been little analysis of clinical characteristics. In this study, clinical characteristics of thyroidal disease patients who visited Kyung-Hee oriental hospital from January to July 2004 were analyzed. Methods : A total 86 patients diagnosed as hyperthyroidism, hypothyroidism or thyroid nodule were selected. Clinical history, including sex, age, symptoms, disease duration and methods of previous therapy and thyroidal test, such as thyroid function test (TFT), thyroid scan and other thyroid examinations. Results : In distribution of onset age and sex, the patients who have visited oriental hospital with thyroidal diseases showed similar characteristics with typical patients. In clinical symptom, the most frequent clinical sign was fatigue in both hyperthyroidism and hypothyroidism, which differs from the classical characteristics of those diseases. Most patients complained the unresolved symptoms, some of which are attributable to abnormal thyroid hormone secretions, in spite of western therapy with anti-thyroidal and hormone supplement agents. Conclusions : In oriental therapy, it will be necessary to consider the unique clinical features of thyroidal diseases different from classical patterns, and this study suggests that oriental therapy is a good alternative method for patients whose first treatment with western agents failed. Furthermore, more public information to these patients about oriental medicine would be helpful to increase cure rates, and give various choices to patients with thyroid diseases.

The purpose of this study were to analyze the clinical correlation between the thyroid autoimmune antibodies (anti-TPO Ab, anti-TG Ab, and TSH) and the maximum standardized uptake value ($SUV_{max}$) base on the Hashimoto's thyroiditis and the Graves' disease in diffusely $^{18}F-FDG$ uptake of the thyroid gland to the PET/CT image. To achieve this, we was performed the PET/CT examination for the 1,097 subjects from May 2010 to April 2013 in the health screening, and was detected the diffused FDG thyroid uptake, and was additionally performed the thyroid function test (TFT) and the ultrasound (US). As a results, the autoimmune thyroid disease with the diffused FDG thyroid uptake were discovered 39 patients (3.9%), of this, the Hashimoto's thyroiditis was 43.6% and the Graves' disease was 23.1%. Hashimoto's thyroiditis was shown the positive reaction of high titer between the anti-TPO Ab and the anti-TG Ab level, and the correlation coefficient between the $SUV_{max}$ and the anti-TPO Ab was a statistically significant (r>04, p<0.05). Also, Graves' disease was shown the positive reaction of high titer most of the thyroid autoimmune antibodies, and the correlation coefficient between the $SUV_{max}$ and the anti-TPO Ab was a statistically significant (r>05, p<0.01). Therefor, when have a high standard of the $SUV_{max}$ due to the diffusely $^{18}F-FDG$ uptake of the thyroid gland, Hashimoto's thyroiditis and Graves' disease were proportionally increased the anti-TPO Ab and TSH level, respectively. The correlation coefficient between the $SUV_{max}$ and the thyroid autoimmune antibodies will be the most influential criterion that was a standard of judgment for the epihpenomenon of the autoimmune thyroid disease, and it will be available for the clinical application.
